Questions
How big is the LM317 Regulator PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LM317 Regulator use?
15 parts, built around the PV36W103C01B00. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the LM317 Regulator KiCad files?
From the Daniel-BO/PCB_Design repository on GitHub, at the commit this page was made from: the board is LM317_Regulator/LM317_Regulator.kicad_pcb and its schematic Dev_card_Pic16f819/Dev_card_Pic16f819.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LM317 Regulator design in my own project?
Its repository states no licence, so its author keeps all rights: ask Daniel-BO before reusing the design.
